My GTM Build Site
I would like to invite you to my Gen 2 GTM build site. On the following page's you will be able to follow my progress in building a Factory Five Racing Gen 2 GTM. This will be my first build and I hope that it will not be my last build.
I anticipate this will take me about 3 years to build. Well this is how much time I have set to complete my Factory Five GTM. I hope that this will be an informative build and would like your feed back.
I would also like to say thanks to Smithgtm, RumRunner and Spytech for the detailed web sites. Also thanks to Brian486 of GSI Motor Sports. Each of these Guys have sure helped me with different parts of the build. Each of these builders are on the Forums FFCars.com and the Factory Fives Forum. So a big THANK YOU and keep up the good work.
